1. 21. Characterising Weak Interactions in Solution. : An NMR Spectroscopic Approach

   Författare :Scott Wilcox; Máté Erdélyi; Chris Hunter; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

   Sammanfattning : Detecting and characterising weak interactions in dilute solutions is challenging. This thesis focusses on the development of a new NMR spectroscopic strategy to do so, whilst also investigates a newly proposed type of weak interaction in solution with currently available NMR techniques.

3. 22. Designing Urban Road Congestion Charging Systems : Models and Heuristic Solution Approaches

   Författare :Joakim Ekström; Jan Lundgren; Anders Karlström; Linköpings universitet; []
   Nyckelord :transport modeling; congestion pricing; network design; bi-level optimization; toll locations; traffic assignment; user equilibrium; collection cost; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The question of how to design a congestion pricing scheme is difficult to answer and involves a number of complex decisions. This thesis is devoted to the quantitative parts of designing a congestion pricing scheme with link tolls in an urban car traffic network. LÄS MER

   Sammanfattning : Regulations are argued to have the answer to solving various social and economic problems that society faces today (e.g., climate change, tax evasion, etc.). LÄS MER

5. 24. Amphiphilic Molecules in Aqueous Solution

   Författare :Gerd Persson; Göran Lindblom; Håkan Edlund; Björn Lindman; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liquid crystal; phase diagrams; counterions; alkylpyridinium octanesulfonates; 1-monooleoyl-rac-glycerol; n-octyl-β-D-glucoside; cubic phases; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : The aim of this thesis was to investigate amphiphilic molecules in aqueous solution. The work was divided into two parts. In the first part the effects of different counterions on phase behavior was investigated, while the second part concerns the 1-monooleoyl-rac-glycerol (MO)/n-octyl-β-D-glucoside (OG)/2H2O-system.

7. 25. Ozone chemistry in aqueous solution : ozone decomposition and stabilisation

   Författare :Margareta Eriksson; Lars Kloo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi;

   Sammanfattning : Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. LÄS MER
